GAS BURNER.

Application filed January 3, 1928.

This invention relates to a gas burner con-` struction.

An important object et the invention is to simplify the construction of gas burners and to assemble the parts of such in a manner which will permit a more convenient removal of the mixing element i'or the purpose of cleaning, and as convenient a replacement said element into its operative position.

A further object is to combine with the convenient removable feature an arrange ment of parts which will safely retain the removable element in its operative position during use.

@ther objects and advantages may hereinafter appear.

iteierring` to the accompanying drawings, which illustrate a preferred embodiment of the invention Figure 1 is a plan view of my newly in vented gas burner provided with 'tour burners.

Figure 2 is an enlarged vertical section of two of the burner elements shown in Figure 1, the line 2-2 on Figure 1 indicating the plane of section, except that one of the burner elements and part of the supply conduit is shown in side elevation.

Figure 3 is a view taken on line 3-3 of Figure 2. In this view a burner element is shown slightly raised and partly swung out from the operative position preparatory to its complete removal.

Referring` in detail to the drawingsa near the base of the frame 5 is the horizontal supply tube 6 which by preference and as shown is secured to the end Walls 7 of said 'trame by short arms 8 cast integral with said supply tube 6. Upon the supply tube are supported the mixing tubes 9 and 10, two of which are shown in. the drawings, but it is to be understood that the number of these mitw ing tubes may be varied as desired. The lower end ot each mixing1 tube is provided with an expanded portion 11 desirably bellshaped- In order to support the mixing tubes there is provided for each tube a spider-dike construction preferably formed integral with the supply tube 6. This spider-like construction is shown as consisting of the short oppositely disposed. arms 12 and 13 which extend crosswise oi the supply tube 6 and which cooperate with the lugs 14 and 15 located at right angles to said arms 12 and 18 and foi-ined upon the upper side of tube (i. The end portions of said arins 12 and 18 are pro Serial lto. 244,312.

vided with the upstanding lugs 16 and 17 and each of these lugs has an internal shoulder 18 upon which the base 11 rests, the upper extremity oi the lup)` 17 serving to center and hold in place the bell-shaped part 11 by reason of external contact therewith. rthe lues 1a and 15 likewise have internal shoulders .20 to cooperate with the other pair of lugs in holding` in place the lower end of the mixingl tube.

Each of the mixing` tubes upper end with a hollow head 9.1 which is expanded in the direction et the length oi the supply tube G, and as shown in section` above the mixing` i top with a pair oi? burner outlets 22 havinn restricted oriiices Q8 which in the present oni bodinient are formed as parallel slots between the bars or in'iperfora'tc burner elements 2d.

Above the burner heads 21 is a hoi-Frontal plate 25 which has a rectangular opening; 2G to forni an open space above each pair of burner heads 21. At cach end of this space 2G is a downwardly extending' pair of lues 27 or 27 which are suiliciently spaced apart to receive between thein an ear Q8 provided at each end oit the head 21. When the mininn,1 tubes are seated upontheir supporting shoulders 18 and 20 there remains above the ears 28,'as well shown in Figure 8, a clearance 29 which permits each tube together with its burner head to be raised slightly and then swung to one side to the position shown in dotted lines in this figure for the purpose of its complete removal and cleaning. Each pair of lugs 27a -forms a centerinn device which is common to two adjacentoininiing tubes. i

The pair o't downwardly extending` lues 27 at one end oitl the opening- 26 is located such distance from the eorresponflinn1 pair of lugs at the other end oi? said openinn` that the burner head 21 tits lengthwise between these pairs of lugs. Therefore this construction forms a centering1 device which keeps the burner tubes from incliniiigI in any direction and yet permits their convenient removal in the manner already described.

The supply tube 6 is provided with any desired gas-;teeding` element 8O and has the pas supplied by the leed pipe i1 controlled by the gas valve 32. 'A

In the drawings the main :traine 5 is shown provided with an end wall 7 and a back wall 33 but any suitable supperting` `traine may Je provided. n

provided at its tube 10 is provided at its v The vposition of a radiator heating element H is indicated in dotted lines.

I claim: g Y l. In a burner construction, the combination with an elongated mixing tube the top of which is open and forms a burner elementand a frame to support said tube in an upright position, of centering means external to said burner element for the top of said tube permitting a limited upward movement thereof, and a plurality of supports arranged in .circular formation, the base of said tube rest-ing upon .said supports, and centering means external tosaid base forming a part of said supports, the aforementioned npward -movement of said tube being sutiicient .to clear the base thereof from said centering means to permit the lower end of said tube to be swung out from said supports preparatory to the complete removal of said tube.

2. In a burner construction, a frame, a plurality of upright mixing tubes mounted side by side in said frame, each of said tubes having at its upper end diametrically opposite radially extending ears which extend toward the adjacent mixing tube, there being downwardly extending paired lugs on said frame between adjacent burners which afford a centering device common to the underlying ears of two adjacent mixing tubes, and centering means. for the base portions of said mixing tubes extending slightly above their lower ends, the lugs which form the aforementioned upper centering device permitting a sutlici ent upward movement of each mixing tube to allow its lower end to swing clear of the lower centering means.

3. In a burner construction, a tubular mixing chamber having a burner outlet at its u perend and an open lower end, a spiderli e support upon which the lower end of saidY tube rests, said support consisting of radial arms having projections which are located slightly beyond the external periphery of the lower end thereof, and centern ing means for the burner end of said tube permitting a sufficient upward movement thereof to raise its lower end above the aforementioned projecting means ranged therearound, to permit of its removal from the. other portions of the burner construction.

4. In a burner construction, a tubular mixing chamber having a burner outlet at its upper end and an open lower end, a spiderlike support upon which the lower end of said tube rests, said support having radial arms provided with projections which are located slight-ly beyond the external peri phery of the lower end thereof, centering means for the burner end of said tube permitting a sufficient upward movement thereof to raise its lower end above the aforcnientioned projecting means ranged therearound, to permit of its removal from the other portions of the burner construct-ion, a fuel l'eed supply out-let arranged within said spider construction to supply fuel to the open lower end of said mixing tube.

5. In a burner construction in combination, an elongated upright mixing tube, provided at its upper end with burner outlets which extend across the upper end of lsaid tube; and at its lower end with a support. from which it may be disengaged by a `slight upward movement, a centering construction located at the top of said mixing tube, said centering construction comprisimv two pairs of downwardly extending lugs, said pairs heilig located diametrically opposite to each other with respect to the top olIV said mixing tube and the lugs of each pair being in spaced relation to each other, there heilig ears provided on said burner head which extend between said lugs, a limited upward movement of said ears between said lugs be ing permitted to disengage said mixing tube from its support preparatory to its removal.

In testimony whereof I allix my signature.
